Odd things can lead to some Macs starting up or waking up spontaneously. Here’s one solution to those mysteries.
M1
Peace of mind about how your new MacBook Pro will cope with its notch, next week’s release of macOS 12.0.1, and a pause for Universal Control.
Why did Apple release three public betas in a week – macOS 12.0, 11.6.1 and Catalina Security Update 2021-007?
Soon M1 Macs will be able to boot from two major versions of macOS, and with new models coming, users are going to have more complex systems. How will Recovery cope?
Although there doesn’t appear to be any straightforward way to run command tools or scripts only on Efficiency cores, there are ways and means.
Prior to 10.4, Mac OS X used cron, then scheduling became part of the job of launchd. Later Apple added a new subsystem, Duet Activity Scheduler, which continues to evolve.
Asymmetric Multiprocessing (AMP) can bring great economy in power and heat production. So why don’t we make better use of it on M1 Macs?
What are the penalties in real-world use for running your code on Icestorm cores, using around 10% of the power used by Firestorms?
Recovering from one regular panic should be straightforward. But what if it’s a boot loop, in which your Mac tries to start up, panics, restarts, in an endless loop? Don’t panic: here are the solutions.
The cores in the M1 and the chip itself are thoroughly Apple designs, and work hand-in-glove with macOS using techniques like out-of-order execution and hints to optimise performance.
